" This slab was brought forward by Sir Roderick Murchison at the 

 nieetiiio- of the British Association, and the footprints thereon, were 

 declared by those who have studied this branch of the science, to bo 

 the traces of a crustacean. 



While speaking of Paleozoic crustacean?, I may recall to your 

 memory the first discovery of the limbs of that remarkable Silurian 

 " lobster," the " Pterygotus problematicus," by Mr. Scobie, and 

 which is described in the Geological Journal by Mr. Strickland and 

 Jlr. Salter. I give the passage at the commencement of Mr. Salter's 

 paper in extenso — " The limbs of this interesting Silurian fossil not 

 havino- hitherto been discovered, the present specimen is of consid- 

 erable interest, as connecting it satisfactorily with the species so 

 fully figured by Agassiz, which Avas obtained from the basement 

 beds of the Old Red Sandstone of Forfarshire. But though of the 

 same o-enus with the Scotch fossil, it presents characters that spe- 

 cifically difl'er." Not more than a fortnight since my attention was 

 called to a collection of Upper Silurian fossils in the cabinet of 

 Mr. Richard Banks, of Kington, and on examining those specimens 

 I found he possessed a large drawer full of the very fossils Avhich 

 Pala-ontologists have so coveted to obtain. They were obtained 

 from the '• Tilestones " at the base of the Old Red Sandstone, at 

 Kino-ton ; and what with the feet, plates, and claws (one of which 

 is even more perfect than the Hagley specimen), I believe that from 

 Mr. Banks' collection, an Owen or Agassiz would restore the 

 Pterygotus, even as the Seraphim of the Scotch quarrymen stood 

 forth, plate to plate restored, a monument of creation and design ! 

 Mr. Banks has kindly promised, on the first opportunity, to forward 

 his fossils to Mr. Salter, for examination and description."' 



* "To<Tether with the Pterygoti, Mr.Banks found fossils formerly confounded 

 with the genus Cephalaspis, Ag.,but now separated. The species are new, but 

 much like C. Lloydii, As;., hitherto known only in the overlying Old Red." 

 (Journal of Geological' Society, Feb. 1, 1856, p. 23.) " Ilinianopterus 

 Banksii," a remarkable crustacean, found by Mr. Banks, is described by Mr. 

 Salter, paije 32 of the same Journal. An excellent engraving of "Leptocheles," 

 or triple tail spines of a Stomapod crustacean, in the possession of Mr. Light- 

 body a member of the Woolhope Club, is engraved plate 8 of the Edinburgh 

 New' Phil. Journal, Oct., 1855. The Club have to thank Mrs. Salwey, of 

 Ludlow, for the drawing from which the engraving was executed. — W. S. S.,
